I have a privacy preserving technology that could conceivably help with the Germanwings crash of 2014. The idea would be there is a long list of issues that would prohibit a pilot from flying...

I'm guessing that a list might look like this:

• Overwork (no sleep)
• Simulator experience, test results
• Medical issues (temporary)
• Drug tests
• Psychological issues

A list of medical providers would link the results together, anonymously, and during the pre-flight check, the ID card would be scanned and rather than a specific issue being highlighted, (depression), the pilot would be asked to rest for a while. No system would know why the rejection occurred, except for the pilot himself.

This might for a balance of privacy, safety, and accountability without compromising need to know.

That being said, I would appreciate any official, or carrier specific list of reasons a pilot would be rejected from flying. Supplemental information would be helpful as well (your thoughts about this solution)
